The BUN Creatinine Ratio Test compares blood urea nitrogen (BUN) to creatinine levels to assess kidney function and hydration status. A high ratio may indicate dehydration, gastrointestinal bleeding, or high protein intake, while a low ratio can suggest liver disease or malnutrition. Doctors order this test with kidney panels to evaluate fatigue, swelling, or abnormal lab results. Results help diagnose renal issues and guide treatment planning.
